Inlays and Onlays

When Should You Consider Inlays and Onlays?

Inlays and onlays are fillings consisting of porcelain, gold, or composite resin- bonded together to the damaged area of the tooth. Dental inlays and onlays are a dental procedure that is used to restore a decayed or damaged tooth to its original condition and can actually strengthen it. The technique of inlays, involves fabricating the restoration outside the mouth, using dental impressions. An onlay is the same as an inlay, except it covers the area where the missing cusp would be. This is different from a crown, that covers all surfaces of the tooth. An onlay is a more substantial reconstruction.

In the past, gold was the material of choice for inlays and onlays. Porcelain has now become more popular as the substance that can better match the natural color of your teeth.

The process for Inlays and Onlays

Inlays and Onlays will require 2 appointments to complete the procedure.
First visit: the damaged or decaying area of the tooth is removed and the filling may be replaced. Then the tooth is prepared for the onlay or inlay. An impression is made by your Gentle Dental dentist, and sent to the lab for fabrication. A temporary sealant is then applied to the tooth.

Second visit: the temporary sealant is removed and the onlay or inlay is then bonded to the tooth, and polished to a smooth finish.

Benefits of inlays and onlays

A traditional filling can reduce the strength of a natural tooth by up to fifty percent. Onlays and Inlays are bonded directly onto the tooth, using high strength resins. This results in increasing the strength of the tooth by up to seventy-five percent. Because of this, they can last from ten to thirty years.
